I am doing a custom-build router, probably using pfSense, but maybe Untangle. I need it to reach gigabit speed, or at least 900 Mbps minimum. Was planning to use Intel EXPI9402PT in the x16 PCI-e slot of a Gigabyte GA-B85M-DS3H-A motherboard, but someone on another forum said I need a Intel X540T2 NIC instead. I Would like a second opinion please!
